LEO NICHOLAS GRONER, OF ST. THOMAS, MISSOURI.

LACE CUTTER.

Application filed November 1, 1921.

T 0 all whom it may concern:

Be it known that I, Lno N. GRoNnn, a citizen of the United States, residing at Thomas, in the county of Cole, State of Missouri, have invented a new and useful Lace Cutter; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to lace cutters, and has for its object to provide a device of this character, which is compact, simple in construction, and so constructed that laces, such for instance shoe laces may be accurately cut from waste pieces of leather or old shoe leather.

A further object is to provide a lace cutter which may be adjusted so that shoe laces of different widths may be cut from discs of leather.

A further object is to provide a lace cutter comprising a base, aguiding flange carried by said base, said base having disposed adjacent thereto, an adjustable cutting blade whereby laces of different widthsmay be out. Also to provide an adjustable spring finger overlying the guide flange, and the space between said flange and the cutting knife and forming means for guiding the severed portion of the lace after it is severed fromthe body of the disc of leather.

With the above and other objects in view the invention resides in the combination and arrangement of parts as hereinafter set forth, shown in the drawings, described and claimed, it being understood that changes in the precise embodiment of the invention may be made within the scope of what is claimed Without departing from the spirit of the invention.

In the drawings Figure 1 is a front elevation of the device.

Figure 2 is a vertical sectional view through the lace cutting device taken on line 22 of Figure 1.

Figure 3 is a horizontal sectional view on enlarged scale and taken on line 33 of Figure 1.

Referring to the drawings, the numeral 1 designates a base, which may be secured to any suitable support, and supported in a vertical or horizontal position. The base 1 is provided with a transversely disposed slot 21, in which is slidably mounted the elongated portion 3 of an outwardly extending Serial No. 512,057.

knife blade 4, which'blade is provided with a cutting edge 5 extending outwardly from one face of the base at substantially right angles. Extending through the portion 3 of the knife 4 is a bolt 6, which bolt extends through elongated slots 7 in the'base 1 and is provided with a thumb nut 8,'by means of which the knife 4 may be clamped in various positions in relation to the end wall 9 of the slot 2. Extending longitudinally and secured on the outer face of the base 1 is a guide plate 10, the flange 11 of which has its outer face in registration with the end of the slot 9, thereby allowing a close adjustment of the knife blade edge 5 in relation to the guide plate, said guide plate having its other flange 12 secured to the base by means of securing devices 13.

At the present time small pieces of waste leather are of very little value and hence are in many instances a loss to a manufacturer of leather goods. When it is desired to form a shoe lace, a disc shaped piece of leather 14 is placed on the base 1 with its periphery in engagement with the flange ll of the guide plate and the disc is rotated with the edge of the disc in engagement with the cutting edge 5 of the knife 4, the operator guiding the disc during its rotation and keeping the same in close engagement with the guide flange thereby causing a strip of leather to be formed, which strip is of uniform width. During this shoe lace forming operation, if the operator so desires he may grasp the shoe lace 15 which is being formed for assisting the severing operation. To prevent the shoe lace or the disc from moving upwardly during a shoe lace forming operation, a spring finger 16 is provided, which spring finger extends through a recess 17 in the flange 11, and overlies the space between the knife edge and the outer face of the flange 11, thereby engaging the upper edge of the shoe lace as it is formed. The finger 6 is disposed on a raised portion 18 carried by the base, and has extending therethrough and through a slot 19 in the base 1, a bolt 20. By loosening the bolt, it will be seen that the guide finger 16 ma be adjusted as desired according to the width of lace being formed and the distance of the knife edge 5 from the guide flange 11. By providing a spring finger it will be seen that a slight variation in the thickness of the disc 11 will be accommodated thereby preventing jamming of the lace asit is formed.

The invention having been set forthwhat is claimed asnew anduseful is:

1. A device for forming laces from pieces of material, said device comprising a base having a transversely disposed slot therein,

a guide flange carried by said base adjacentthe inner end of said slot, a plate slidably mounted in said slot means whereby said plate may be adjusted inwardly and outwardly and held in various positions in said slot, the inner end of said plate being provided with an outwardly extending severingmember disposed substantially paralrasoaee guide flange and means whereby saidspring fingermay be adjusted inwardly and outwardly.

2. A device for forming laces from pieces of material said device comprising a base, a guide flange carried by said base, an adjustable knife in parallel relation to said guide flange and adjustable in relation to said guide flange and an inwardly and outwardly adjustable guide finger carried by the base and extending through a notch in the guide flange and overlying the space between theguide flange and the knife.

In testimony whereoi I have signed my name to this specification in the presence of two subscribing witnesses.
